Detective Fitch came to blows with a prominent businessman who says he knows about the cop's past in New York.

Real-life issues in Detroit -- copper theft, preservation, squatting, foreclosure, blight, and a foot chase through Michigan Central Station -- were front and center in one of two crime storylines.

Detective Washington is back on the homicide beat, but struggles with his shooting injury.

The show itself showed vast improvement in dialogue and production.

This week:

Finally! Two murder storylines that are worth watching. Without giving away too much, I can promise that both will keep your interest. One focuses on a dead car wash owner, and another on an aspiring music producer found dead downtown.

Remember the epic pop/soda debates we've been having so far this season. Pay close attention to one of the murder scenes, and you'll see that issue handily resolved.

Fitch may not be the only cop with a secret. Detective Stone, a former narcotics unit officer, may be hiding something of his own.

And speaking of Fitch, we learn a little bit more (yes I know, little by little) about his eccentricities. Fitch continues to hawk over Washington, who is still bumbling around with his nagging wife.

Sgt. Jesse Longford is still staring down retirement.

Look for a bevy of guest stars, including Xzibit (who grew up on the city's east side), Keesha Sharp (Monica of The CW's "Girlfriends"), J.D. Williams (HBO's "Oz" and "The Wire") and Nicki Micheaux (another Detroit native who starred in ABC Family's "Lincoln Heights").

No car chase or cliffhanger in this episode, but there is a very intense scene toward the end.
